Steel A11 vs ASP 2030
Steel · grade comparison
Steel A11 and ASP 2030 are both steel grades. ASP 2030 is the stronger of the two: tensile strength 950 MPa (138 ksi) against 900 MPa (131 ksi) for A11, about 6% more. ASP 2030 is the more ductile: elongation 12% versus 8% for A11, and ASP 2030 is harder (300 HB vs 269 HB). A11 is lighter (7.41 g/cm³ vs 8 g/cm³ for ASP 2030) and A11 runs hotter in service (425°C vs 300°C continuous). On the shop floor, ASP 2030 sits in a lower cost tier (high, $$$$) than A11 (specialty, $$$$$).
A11Choose it when weight is the constraint, or when the part sees heat.
ASP 2030Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
A11 vs ASP 2030: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

A11 vs ASP 2030 — frequently asked
Is ASP 2030 stronger than A11?
Yes. ASP 2030 has a typical tensile strength of 950 MPa (138 ksi) against 900 MPa (131 ksi) for A11 — about 6% more.
Which is cheaper, A11 or ASP 2030?
ASP 2030 is the lower-cost material: it sits in the high tier ($$$$) while A11 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, A11 or ASP 2030?
ASP 2030, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for A11; for welding the order is ASP 2030 first (poor, 20/100) then A11 (poor, 15/100).
